ALEXANIER NESTOR, OF CHICAGO, ILLINOIS.'

BREAD-CUTTER.

Specification of Letters lPatent Application sled october 2o, 1917. serial No. 197,524.

' To all ywhom 'it may concern:

Be it known that I, ALEXANDER Nns'roiz, a citizen of Russia, resident of Chicago,

- county of Cook, and State of Illinois, have plished by the movement of a single crank;

A- further object is to provide means with which the bread loaf may be conveniently and readily secured in connection with the traveling element, irrespective of its shape or size Within reasonable limits.

' These and other like objects are attained by the novel construction and combination of parts hereafter described and shown in the accompanying drawings, forming a material part of this disclosure, and in which- Figure 1 is a side elevational view of a machine, made in accordance with the invention, parts being broken away inrorder to show the construction.

Fig. 2 is an enlarged transverse sectional view showing a preferred form of thevbread engaging means.

Fig. 3 is a vertical sectional view taken on line 3-3 of Fig. 1, and

big. 4 is a similar vertical sectional view taken on line 4-4 of Fig. 1.

The machine comprises a pedestal 10, from which arise standards 11, constituting a frame in which is journaled a shaft 12, havingv affixed u on it a bevel gear 14, mesh.-

' ing wlth a mating gear 15, the latter upon the end of a transverse shaft 16, actuated. by an extending crank handle 17, and carried in support bars 18 and 19. Y

Also ixed u on the shaft 12, closely adjacent to one o the standards 11, is a spur gear 20, the same meshing with a spur pinion 21, which is attached upon the outer end of a coarse-threaded screwv 422, journaled in the standards 11, near their upper ends.-

VEngaged with the screw 22, are internally threaded brackets.23,.the same being rigidly attached toa platform 24, near one of its edges, -the plate being further supported upon other brackets 26, s'lidably mounted Patented Aug. 2o, 191s..

upon ashaft 27, secured parallel to and in the same plane as the screw 22.

Engaged with the platform 24, at each of its four corners. are tension springs 28. their upper ends connecting with a plate 30. carrying on its llower side a plurality of spurs 32, the plate being guided by a longitudinally disposed vertical plate 34, secured at its lower edge to the standards 11.

Also rigidly secured to the shaft 12 is a hub 36, of a cutter 38, having a spirally formed cutting edge 39, the same being arranged so that the inner partof the spiral is adapted to make Contact with the outer surface of the loaf when the same is brought into engagement with it by rotating the handle 17, which, as will be seen, not only serves to actuate the cutter, but advances the platf form on which the bread loaf is confined, the. cut slices being delivered upon a plate v40, substantially level with the platform 24, and supported by the standards 41 from the pedestral 10. v

In the modified formshown in Fig. 2, a similar contrivance is observable in which the tension springs 28, engage with the platform 24, at their lower ends and a sectional plate at their-upper ends, the plate being comprised of outer elements 45, with which are hingedly engaged inner leaf elements 46 by pins 47, there being set in the upper surfaceof the inner elements 46 projections 48,

between which is extended a tension spring 50 so as to hold them normally horizontal. Connecting` the elements 46, is a central joint linlr52,'in which is rigidly secured a stem 53, the same extending upward and being furnished with an operating knob 54.

Spurs 56, are secured to the lower side of the elements 45 and 46, in aV manner clearly indicated and which are adapted to enter and engage with the upper surface of a loaf of bread entered therebetween.

In this form' of construction', by raising the knob v54, the upper sectional plate, comprised ico.V

of the hinged elements Will be readily raisedl permitting convenient'insertion of the brea loaf therebelow,A and it will be noted that the construction` of the upper plate is such as Awill permit it to conform readily to the upper surface of the loaf, which frequently is curved and irregular.

in operation, the bread loaf having been placed in the carriage upon the platform 24, and there held in position by the spurs, the crank handle 17 is actuated, causing 'the platform to avence in proportion according to the gearing and pitch of the screw 22,' while at. the same time the knife soveis the loaf into slices of predetermined thickness in an easy and convenient manner.

Haring thus described my invention what olaim'as new and desire to secure by Le;u ters Patent, is

1. In a bread cutter, the combination with a frame a platform mounted to move longitudinally thereon, means for actuating saicl platform, and a revoluble cutter adapted to sever a bread loaf, of a clamping means for a bread loaf, said clamping means comprising e plurality of hinged plates, spring connecions between the outermost of said plates and said platform, means for holding said' plate elements normally in e horizontal plane, and means for raising said elements 'gemene formes?L with said sectional plate eepted to engage with the bread loef, means for holding said sectional plate normally horizontal, means for raising said sectional plate so that a bread loaf may be insertec hereunder, means Jfor advancing said` platform, and. means for slicing the bread loaf,y said siicing 'means and advancing means acting coinclf clently. Y

In estimony whereof have axel my signature.

ALEXANDER NESTOR.
